Editor guide

How to use P&P Code Studio

Choose one workspace category first. The editor then shows only the tools relevant to that task.

Choose a category

Code edits HTML, CSS and JavaScript. App tests an endpoint. Social contains network embeds. Embed handles URLs and iframe code. Documents opens local files.

Add your source

Paste a URL or embed code, or choose a local file. Press Enter to create the preview.

Work live

Auto-run keeps the preview synchronized while you edit. Use Run whenever you want a manual refresh.

Adjust the view

Resize or hide columns, test desktop, tablet and mobile, and choose Partial, Normal or Full zoom.

Open the pop-out

The detached preview stays synchronized and has its own zoom controls. Use Open original if a service blocks iframe display.

Copy or export

Copy the active code or download it locally. Online sharing and endpoints become available after sign-in.

Start easily, expand when needed

The editor grows with your project.

Core testing stays available without an account. Sign-in is required only when work needs to be saved or published online.

How Code Studio works

1

Write code

Edit HTML, CSS and JavaScript directly in your browser.

2

Preview live

Changes appear in the preview immediately.

3

Export

Download, share or use the result in your own project.

Edit HTML online

Code Studio is a free online editor for HTML, CSS and JavaScript. Write markup in the HTML tab and see the result immediately—without a local development environment, build process or account.

Write and test CSS instantly

Adjust layout, colors, spacing and animations in the CSS tab. Every change renders immediately, making selectors, media queries, Flexbox and Grid easy to verify.

Test JavaScript

The JavaScript tab runs your code in the preview. Syntax errors appear in the status bar and runtime errors appear in the preview—ideal for scripts, event handlers and quick experiments.

Templates, import and export

Start with a landing page, contact form or product-card template, or import an existing file. Export a complete HTML file or download HTML, CSS and JavaScript separately.

Responsive preview

Use the device controls to test desktop, tablet and mobile widths and catch layout problems before publishing.

Your data stays local

Code Studio processes code entirely in your browser. Files are not sent to a P&P server; anonymous autosave uses only your browser's local storage.
